Problems solved by technology
At present, most PCB boards are equipped with fuses. Once the circuit is over-current, the fuse part will be blown, forming an open circuit between the two pads, resulting in the unusable overall circuit. This will not only affect the service life of the PCB board, but also directly cause the car to stop running
The PCB board needs to be repaired, and the repair process is relatively complicated and difficult to implement

The invention provides a PCB with a fuse blowout function and a preparation method thereof. A blowout assembly is independently connected in parallel. When current overflows, a circuit can be protected, and the use of other loads of the vehicle is not influenced. When the fuse blows out, only the damaged fuse needs to be changed, and the whole PCB does not need to be repaired. Meanwhile, the heat resisting property and the heat conducting property of the PCB are substantially improved. The requirement for heat dissipation of the high-power PCB can be met completely. The service life of the PCB is prolonged.
Description
technical field [0001] The invention belongs to the technical field of PCB processing, and in particular relates to a PCB board with a fuse function and a preparation method thereof. Background technique [0002] In the entire automotive electrical system, the automotive electrical box is a very important key component. It is responsible for distributing power to each load, controlling the current of each load, and ensuring the safe operation of each load. [0003] With the development of the automobile industry, the requirements for high-grade, humanized, multi-functional, high safety and environmental protection of automobiles are getting higher and higher, and the internal load of automobiles is also increasing. Therefore, the power consumption of the electrical system of the whole vehicle The amount of electricity is getting bigger and bigger, causing the heat of the car's electrical box to be higher and higher, and the risk of burning the electrical box or even burning ...
